In order to shadow Gautham thoroughly, Avinash turns to his friend Venkatesh Sivakumar aka. Venkat (Geethendra Sugendra), the CEO of the newly founded company InnoTech. Together, they both offer Gautham a job at InnoTech for a trial period of one month, in which Avinash is to thoroughly note Gauthams behavior and reactions in certain conditions.nnIn spite of finally getting a job, Gautham has not fulfilled his purpose yet. He is still searching for the significant values in life. His greatest wish is to obtain a caring relationship, which he never had, with his sister, Soumya (Stefeja Vasantharasan). Whether he gets to live life, as he wishes it, and thereby fulfills his purpose forms the crux of the story.nnParanoid Patient is a film, which deals with a man who is in search of compassion, friendship and love.
